Abstract

본 발명은 움직임 적응형 순차 주사 장치에 관한 것으로서 입력된 화상 신호를 한 필드 단위로 지연시키기 위한 필드 지연부(20)와; 입력된 필드 신호를 한 라인 단위로 지연시키기위한 라인 지연부(22); 동일 팰드내의 한 라인과 상기 지연된 다른 라인의 평균값을 발생시키는 라이 평균값 발생부(24) 움직임 정보에 따라 사익 필드 지연부(20)로부터의 입력 신호와 상기 라인 평균값 발생부(24)로부터의 입력 신호를 가지고 보간된 라인 신호를 출력하는 믹서(26);및 상기 보간된 라인신호와 입력된 원 화상의 라인 신호 중 한 신호씩 교대로 선택하여 순차 주사하도록 되어진 스위칭부(28)로 구성되어 있으며 화상의 움직임 정도에 따라 발생된 보간 신호을 이용함으로써 특히 움직임이 많은 동화상이 화면에 디스플레이될 때 불연속적인 동작으로 나타나는 현상을 방지할 뿐만 아니라 원래의 화상을 충실히 재현해낼 수 있다는 데 그 이점이 있다.The present invention relates to a motion adaptive sequential scanning device, comprising: a field delay unit 20 for delaying an input image signal by one field; A line delay unit 22 for delaying the input field signal by one line unit; The input signal from the sound field delay unit 20 and the input signal from the line average value generator 24 according to the motion information of the lie average value generator 24 which generates an average value of one line in the same pad and the other delayed line. Mixer 26 for outputting the interpolated line signal with a; and a switching unit 28 is configured to sequentially scan by sequentially selecting one of the interpolated line signal and the input line signal of the input image, the image By using the interpolation signal generated according to the degree of motion of the motion, a phenomenon in which discontinuous motion is displayed, especially when a moving picture with a lot of motion is displayed on the screen, can be prevented, and the original image can be faithfully reproduced.
